W78C32CP-40 - 8-BIT MICROCONTROLLER 

GENERAL DESCRIPTION 

The W78C32C microcontroller supplies a wider frequency range than most 8-bit microcontrollers on 

the market. It is compatible with the industry standard 80C32 microcontroller series. 

The W78C32C contains four 8-bit bidirectional parallel ports, three 16-bit timer/counters, and a serial 

port. These peripherals are supported by a six-source, two-level interrupt capability. There are 256 

bytes of RAM, and the device supports ROMless operation for application programs. 

The W78C32C microcontroller has two power reduction modes, idle mode and power-down mode, 

both of which are software selectable. The idle mode turns off the processor clock but allows for 

continued peripheral operation. The power-down mode stops the crystal oscillator for minimum power 

consumption. The external clock can be stopped at any time and in any state without affecting the 

1.processor.
